Airmar B265LH CHIRP Transducer

When thru-hull transducers are installed with a High-Performance Fairing, the transducer face is parallel to the waterline resulting in a beam that is vertically oriented for maximum echo returns and the best possible performance.  The fairing compensates for hull deadrise and reduces turbulence over the transducer face, which allows tracking at speeds over 30 knots (35 MPH). This installation, when mounted in clean water (forward of propellers and running gear), produces the most effective signal return since nothing on the vessel interferes with the transducer’s active surface. Thru-hull transducers will work with any engine type: inboard, outboard, or I/O.


• Depth & fast-response water-temperature sensor

10° to 6° beamwidth
• 103 kHz of total bandwidth from one transducer
• Covers popular fishing frequencies of 50 and 200 kHz
plus everything else in the bandwidth
• Fishing Profile: Commercial and recreational inshore
and offshore fishing (deep-water canyon and
sea-mount tracking)
• Bronze transducer housing with High-Performance Fairing
• Boat Size: 8 m (25’) and above
• Hull Type: Fiberglass or wood


• 5 to 10 times greater detail and resolution
• 10 to 1,000 times more energy on targets
• Accuracy down to 3,000 m (10,000’)

When Your Living Depends on Finding Fish...
Rely on Airmar’s new broadband transducers for the ultimate fishing mission. Whether you’re a commercial
fisherman, charter captain, or tournament angler, there’s a new game in town! CHIRP transducers enable bottom
detection down to 3,000 m (10,000’) with 5 to 10 times greater detail and resolution so precise it’s possible to
distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to
117 kHz of total bandwidth in just one installation, saving customers time and money.
Airmar…it’s what’s under your boat.

The CHIRP Difference
Traditional marine fishfinders operate at discrete frequencies such as 50 kHz and 200 kHz, use relatively
short-duration transmit pulses, and use narrowband sonar transducers. In contrast, CHIRP (compressed
high-intensity radar pulse) uses a precise sweep pattern of many frequencies within a long-duration transmit pulse
from a broadband transducer, so the equivalent sound energy transmitted into the water is 10 to 1,000 times
greater than a conventional marine fishfinder. The echo energy returning to the transducer, superior to that
generated by a conventional transducer, is then processed by the fishfinder’s DSP (digital signal processing)
computer and displayed in ultra-sharp detail on the display. The combination of CHIRP, a broadband transducer,
and the fishfinder’s DSP, results in dramatically better fish and bottom detection, superior depth capability, and
significantly better performance at speed.

Does YOUR Fishfinder CHIRP?
Only CHIRP/Spread Spectrum sounders using Airmar broadband transducers can operate as a CHIRP fishfinder
system. When Airmar’s new transducer is paired with a broadband fishfinder, the result is 5 to 10 times greater
sensitivity and performance than current fishfinder technology. Packed with exclusive technology like
Transducer ID® and newly engineered piezoceramic elements, Airmar transducers are über sensitive and designed
to automatically sweep frequency bands from 28 kHz to 210 kHz with no tuning necessary. As a result, all targets
detected in the entire bandwidth will be seen on the display rather than only what is identified in traditional
frequencies at 50 kHz and 200 kHz.
Airmar’s complete line of twenty-four (24) CHIRP transducers are available in seven (7) different mounting options
to accommodate almost any hull design. CHIRP transducers are available at Gemeco Marine Accessories
www.gemeco.com and Airmar EMEA www.airmar.com/emea. Visit www.AIRMAR.com for a list of
CHIRP-ready transducers.
